We're dividing 621331 by 7 
Our goal is to divide 621331 by 7.

Step 1:
When dividing 6 by 7, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 7

Advancing to step 2:
7 can be fit into 62 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 56 from 62 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 7

On to step 3:
When dividing 61 by 7, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtracting 56 from 61 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 7

Moving on to step 4:
If we divide 53 by 7, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 887.0
If we take 49 away from 53, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Let's proceed to step 5:
43 divided by 7 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 8876.0
The remainder is 1 after subtracting 42 from 43.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 7

Going ahead to step 6:
7 can be fit into 11 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 88761.0
If we subtract 7 from 11, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 88761.5
Subtracting 35 from 40 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 88761.57
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 88761.571
Deduct 7 from 10 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 88761.5714
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 88761.57142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 88761.571428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 88761.5714285
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 88761.57142857
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 88761.57142857 with a balance of 1e-09.
